ELECTRIC FLATIRON.

Application filed April 14, 1919.

To a?? 'uf/10m z't 71mg/ concern.'

Be it known that I, ALBI-arr E. IAGGoNmu a citizen ot' 'the UnitedStates, anda resident ot' Chicago, in the county of Cool( and State ot'Illinois, have invented certain new and useful Iinl'novements inElectric Flatirons., ot` which the following is a full, clear, and exactdescription.

The invention relates to electric flat irons and its object is toprovide improved means for indicating whether or not current is passingthrough the resistance element.

This object of the invention is attained primarily by providinganindicator which, at a clearly visible point, will by illuminationindicate whether the resistance element is at red heat or not.

The invention consists in the several novel :teatiucs hereinafter setforth and more particularly defined by claims at the conclusion hereof.

In the drawings: Fig. 1 is a side elevation of a fiat iron embodying theinvent-ion. Fig. 2 is a section showing the improved indicator and Fig.3 is a detail section of a moditication.

The invention is illustrated as exemplified in a flat iron comprising abase 4 which may be of usual construction, a handle 5, suitably securedto the base, and a resistance element (i interposed between asbestosinsulation 7, mica insulation 8 and a metal body or filling.r 9 betweenthe mica insulation and the enclosing shell 10. It will be understoodthat current will be supplied to the resistance element in manner wellunderstood in the art.

An indicator comprises a disk 11 having prismal formations on its lowerface and a stein 12 which extends through the shell 1() to a point ontop of the shell near one side thereof. This indicator is made entirelyof glass and, as a result, when the resistance coil is red hot orglowing, the indicator will be illuminated b v the said element, so thatthe upper end will clearly indicate the condition of theresistanceelement.

In Fig. 3, there is shown a modification in which the indicator consistsof a glass tube 16 and a jewel glass 17 held at the upper end of thetube by the shell 10. In this modification, the glow of the resistanceelement 6 illuminates the jewel-glass 17 and clearly indicates thecondition of said element.

The invention is not to be understood as Serial No. 289,949.

restricted to the details set forth, since these may be modified withinthe scope of the appended claims, without departing from the spirit andscope ot the invention.

Having thus described the invention, what l claim as new and desire tosecure by Letters Patent, is:

1. A fiat iron comprising a resistance element adapted to emit lightwhen in operation and a body enclosing said element and having anopening therein to expose a portion of said element to permit anindication oi its condition.

2. A flat iron comprising a resistance element adapted to emit lightwhen in operation, a body enclosing said element and having an openingtherein to expose a portion of said element to permit an indication ofits condition, and a transparent indicator in said opening.

3. A fiat iron comprising a resistance element adapted to emit lightwhen in operation, a body enclosing said element and having an openingthereto to expose a portion of vsaid element to permit an indication ofits condition, and transparent indicating means extending into proximityto said exposed portion of the element and to the exterior of said body.

4. In an electrically heated tool the combination with a tool body of acoil for heating said tool body adapted to emit light when in operation,said tool body having a sight opening` through which a portion of theheating coil is visible, whereby when the current is turned on theincandescence of said portion isvisible, thus giving an indication as tothe fact that the current is on.

In an electric flat iron, a plurality of plates, a heating elementconfined therebetween, a casing for housing said element and one of saidplates, one wall of said casing being provided with a sight opening andone of said plates being provided with an opening in alinement with saidsight opening and exposing a portion of said element.

6. In an electric fiat iron, a casing, a plurality of plates, a heatingelement confined therebetween, one of said plates being provided with anopening to expose a portion of said heat-ing element and said casingbeing provided with a sight opening in alinement with said first namedopening.

ALBERT E. WAGGONER.
